The Production Process
There are a series of operations in the production process that are critical in producing good quality corks. After extracting the cork barks they are carefully selected and criteriously stored in J.A. Veiga de Macedo S.A. warehouse. The cork is left to relax and settle for a period of approximately one year. It enables the cork to mature before the boiling process. Boiling takes place when the cork planks are immersed in a bath of boiling mineral water at about 100 degree Celsius for one hour and 30 minutes. It enables the cork to be:
-free from hydro-soluble substances.
-increase their elasticity and softness.
